British trio Mutya Keisha Siobhan have dismissed reports suggesting they have been dropped from their record label after their comeback release failed to set the U.K. singles chart alight.

The original members of the Sugababes, Mutya Buena, Keisha Buchanan and Siobhan Donaghy, officially reunited last year (12) and relaunched themselves under the new band name Mutya Keisha Siobhan.

They dropped their first single, Flatline, in September (13), but the song only peaked at 50 in the U.K chart, leading to recent rumours suggesting they had split from label bosses at Polydor.

However, Buchanan is adamant there is no truth to the claims and insists the low charting of Flatline was to be expected as they decided against a huge promotional push for the project.

She tells NME.com, "We're still with Polydor. 100 per cent. For us we weren't expecting the single to chart...

"If we'd done more Tv and there had been more promotion around us then we definitely would have had a bigger single. But it did what we wanted it to do... For us, I mean I'm not gonna say chart position isn't important, but we are about the album."

Mutya Keisha Siobhan are currently preparing to unveil their debut album early next year (14).
